dm_test_set...tate_no_crtc(9) β Kernel API Manual β¨
okay so bestie, welcome to the page for dm_test_set_pflip_irq_state_no_crtc π this one lives in the Kernel API Manual and it's short, sweet, and honestly kind of iconic for how little it has to say. it's a KUnit test. that's the vibe. no cap.
πΈ NAME πΈ
dm_test_set_pflip_irq_state_no_crtc β Test pflip irq state with missing CRTC π¦
like, the pflip irq state, but the CRTC? not there. gone. missing. the test is literally about what happens when it's absent, and honestly same energy tbh π
β SYNOPSIS β
void dm_test_set_pflip_irq_state_no_crtc (struct kunit *test );
that's it. that's the whole signature. she's void, she takes one pointer, she does her little test thing π
(yes, keep the space before the ) β that's how it's written, we don't touch it fr fr)
π«Ά ARGUMENTS π«Ά
testβ The KUnit test context π this is the KUnit framework's own context struct, handed to your test so it can do KUnit things. it's the main character of the parameter list (it's also the only one, so like, lowkey by default π)
π SEE ALSO π
bestie. buckle up. there are a LOT of siblings and we are listing every single one, no skipping, periodt π

π‘ friendly reminder bestie: every single one of those is section 9 and that's exactly how they're written β don't go "fixing" the names, they're load-bearing π«Ά
and that's the page!! mwah π source is ./drivers/gpu/drm/amd/display/... and the date stamp says October 2026 β so she's from the future, obviously, main character energy πβ¨ bye bestie, go write some KUnit tests π
